Aplumbing supplies manager realises he has a profit margin of 15%. his total sales for a month came $23,000. how much of this is profit?

The percentage of profit margin that
the plumbing supplies manager realizes that he has = 15%
Total sales for the month made by the plumbing supplies manager = $23000
Then
Amount of profit that has been made
by the plumbing sales manager = 15% * 23000 dollars
                                                    = (15/100) * 23000 dollars
                                                     = 15 * 230 dollars
                                                     = 3450 dollars
So the plumbing manager makes a profit of $3450 in the month as can be seen from the above deduction.
